# GameMode
|
||||
**GameMode** is a daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS.
|
||||
|
||||
A preliminary implementation of a daemon/lib combo to allow games to request a performance mode from the host OS on Linux. It was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is intended to be expanded beyond just CPU power states as needed.
|
||||
The design has a clear-cut abstraction between the host daemon and library (`gamemoded` and `libgamemode`), and the client loaders (`libgamemodeauto` and `gamemode_client.h`) that allows for safe use without worrying about whether the daemon is installed or running. This design also means that while the host library currently relies on `systemd` for exchanging messages with the daemon, it's entirely possible to implement other internals that still work with the same clients.
|
||||
|
||||
Currently using `sd-bus` on the user bus internally for messaging
|
||||
GameMode was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is intended to be expanded beyond just CPU governor states, as there are a wealth of automation tasks one might want to apply.
|
||||
|
||||
Issues with GameMode should be reported here in the issues section, and not reported to Feral directly.
|
||||
|
||||
---
|
||||
## Building and installing
|
||||
GameMode depends on `meson` for building and `systemd` for internal communication. This repo contains a `bootstrap.sh` script to allow for quick install to the user bus, but check `meson_options.txt` for custom settings.
|
||||
|
||||
```bash
|
||||
# Ubuntu
|
||||
apt install meson libsystemd-dev pkg-config ninja-build
|
||||
# Arch
|
||||
pacman -S meson systemd ninja
|
||||
|
||||
git clone https://github.com/FeralInteractive/gamemode.git
|
||||
cd gamemode
|
||||
./bootstrap.sh
|
||||
```
|
||||
|
||||
---
|
||||
## Requesting GameMode
|
||||
|
||||
### Users
|
||||
After installing `libgamemodeauto.so` simply preload it into the game:
|
||||
```bash
|
||||
LD_PRELOAD=/usr/\$LIB/libgamemodeauto.so ./game
|
||||
```
|
||||
Or edit the steam launch options:
|
||||
```
|
||||
LD_PRELOAD=$LD_PRELOAD:/usr/\$LIB/libgamemodeauto.so %command%
|
||||
```
|
||||
|
||||
### Developers
|
||||
You may want to build the request directly into an app. Note that none of these client methods force your users to have the daemon installed or running - they will safely no-op if the host is missing.
|
||||
|
||||
#### Explicit requests
|
||||
```C
|
||||
#include "gamemode_client.h"
|
||||
|
||||
if( gamemode_request_start() < 0 ) {
|
||||
fprintf( stderr, "gamemode request failed: %s\n", gamemode_error_string() );
|
||||
}
|
||||
|
||||
/* run game... */
|
||||
|
||||
gamemode_request_end(); // Not required, gamemoded can clean up after game exits
|
||||
```
|
||||
|
||||
#### Implicit requests
|
||||
Simply use the header, but with `GAMEMODE_AUTO` defined.
|
||||
```C
|
||||
#define GAMEMODE_AUTO
|
||||
#include "gamemode_client.h"
|
||||
```
|
||||
|
||||
Or, distribute `libgamemodeauto.so` and either add `-lgamemodeauto` to your linker arguments, or add it to an LD\_PRELOAD in a launch script.
|
||||

||||

|
||||
## Components
|
||||
|
||||
### Host
|
||||
#### gamemoded
|
||||
Runs in the background, waits for requests, refcounts and also checks caller PID lifetime.
|
||||
Runs in the background, activates game mode on request, refcounts and also checks caller PID lifetime.
|
||||
|
||||
Accepts `-d` (daemonize) and `-l` (log to syslog)
|
||||
Accepts `-d` (daemonize) and `-l` (log to syslog).
|
||||
|
||||
#### libgamemode
|
||||
Dynamic library to dispatch requests to the daemon
|
||||
Internal library used to dispatch requests to the daemon.
|
||||
|
||||
Note: Behaviour of `gamemoded` may change, so `libgamemode` should never be linked with directly.

|
||||
|
||||
#### cpugovctl
|
||||
Small program used to to control the cpu governor.
|
||||
|
||||
Accepts `get` (gets current governor) and `set <GOVERNOR>` (sets the current governor).
|
||||
|
||||
### Clients
|
||||
### Client
|
||||
#### libgamemodeauto
|
||||
Simple dynamic library that automatically requests game mode when loaded. Minimal dependencies.
|
||||
Simple dynamic library that automatically requests game mode when loaded.
|
||||
|
||||
Useful to `LD_PRELOAD` into any game as needed.
|
||||
|
||||
#### gamemode\_client.h
|
||||
Very small header only lib that lets a game request game mode and handle errors. Minimal dependencies.
|
||||
|
||||
Can also be included with `GAMEMODE_AUTO` defined to behave automatically.

## Build and install
|
||||
|
||||
### Daemon and host library
|
||||
|
||||
#### Dependencies
|
||||
* meson
|
||||
* systemd
|
||||
|
||||
```bash
|
||||
# Ubuntu
|
||||
apt install meson libsystemd-dev pkg-config
|
||||
# Arch
|
||||
pacman -S meson systemd
|
||||
```
|
||||
|
||||
```bash
|
||||
git clone <git repo>
|
||||
cd gamemode
|
||||
./bootstrap.sh
|
||||
```
|
||||
|
||||
---
|
||||
## Using with any game or program
|
||||
|
||||
After installing `libgamemodeauto.so` simple preload it into the program. Examples:
|
||||
```bash
|
||||
LD_PRELOAD=/usr/\$LIB/libgamemodeauto.so ./game
|
||||
```
|
||||
Or steam launch options
|
||||
```bash
|
||||
LD_PRELOAD=/usr/\$LIB/libgamemodeauto.so %command%
|
||||
```
|
||||
|
||||
---
|
||||
## Building into a game or program
|
||||
|
||||
You may want to build in functionality directly into an app, this stops the need for users to have to manually set anything up.
|
||||
|
||||
`gamemode_client.h` and `libgamemodeauto` are safe to use regardless of whether libgamemode and gamemoded are installed on the system. They also do not require `systemd`.
|
||||
|
||||
### Using directly
|
||||
```C
|
||||
#include "gamemode_client.h"
|
||||
|
||||
if( gamemode_request_start() < 0 )
|
||||
fprintf( stderr, "gamemode request failed: %s\n", gamemode_error_string() );
|
||||
|
||||
/* run game... */
|
||||
|
||||
gamemode_request_end(); // Not required, gamemoded will clean up after game exists anyway
|
||||
```
|
||||
|
||||
### Using automatically
|
||||
|
||||
#### Option 1: Include in code
|
||||
```C
|
||||
#define GAMEMODE_AUTO
|
||||
#include "gamemode_client.h"
|
||||
```
|
||||
|
||||
#### Option 2: Link and distribute
|
||||
Add `-lgamemodeauto` to linker arguments and distribute `libgamemodeauto.so` with the game
|
||||
|
||||
#### Option 3: Distribute and script
|
||||
Distribute `libgamemodeauto.so` with the game and add to LD\_PRELOAD in a launch script
|
||||
Single header lib that lets a game request game mode and handle errors.
